f 8?* To all whom zt 17mg concern:

Be it known that-I, CARL AUGUST PFEN- NING, a subject ofthe German Emperor,y residing at Barmen, (Rittershansem) in Rhenish `Prussia,Germany, have invented a new and useful Machine for the Manufacture ofButtons, of which the following isfa specification, 'ref'- `erence beinghad to the accompanying drawings.

This invention has been patented to me abroad as follows: In Germany,Nos. 27,881 and 28,621, October 12, 1886; in Canada, No. 25,497,December 6, 1886; in Denmark, No. 864, October 27, 1886; inAustria-Hungary, No. 18,180, October 15, 1886; in Belgium, No. 73,004,May 15, 1886; in Italy, No. 20,181, May

`15, 1886; in Portugal, No. 1,085, December23, 1886; in France, No.175,617, August 20, 1886;

in Norway, No. 172, March 24, 1886; in Sweden, July 24, 1886; in Spain,No. 9,620, October, 1886, and in England, No. 5,446, April 20, 1886.

This invention relates to an improvement upon the machine patented to meOctober 5,

Vpl'oying different machines for different sizes' of buttons. By thepresent machine, by interchangeable parts, 1 can make any size button onthe same' machine, provided said sizeis no greater than the largestbutton which the machine is capable of making.

" In my drawings similarletters refer to simiv lar parts.

Figure 1 represents a perspective elevation of my machine with thebutton-forming cap closed; Fig. 2, a perspective elevation of the sameat right angles to Fig. 1, with the button-forming cap open; Fig. 3, acentral trans verse section through Fig. 1.; Fig'. 4, a detail showingthe method of substituting the ejector and cap for a different sizebutton. y

A represents the frame of the machine, upon in dotted lines in Fig. 1,when the cloth and The plunger O is n then swung over the button-tube D,and the which the other parts are mounted. lThis frame or base has uponits upper side-a subcstantially flat surface, upon which the other partsare mounted. A cylindrical recess, O,

is bored through the plate forthe `reception of the buttontube D andejector E. The ejector is operated by a cam', F,'rotating crank G, as isplainly apparent from the drawings. InY the process of forming thebutton the ejector is first allowed todrop into the position shown f inFig. 4, allowing of the insertion of the ma-y terials to form the buttonwithin the cylindrical cavity thus left. the ejector is then raised intothe position shown in Fig. 3. The cam Fshould have a substantially datportion, F', which' rests beneath the ejector when the ejector israisedto its upper position. The rest of the button After the cap isclosed A forming mechanism is carried upon the cover B, pivoted at J.This cover isy substantially similar to the cover of the machinepreviously vpatented to me. When closed, it is locked into position-bythe bolt K. It carries the button-forming cap L and eyeleti'ng screw-/spindle M.y The kscrew-spindle is turnedby the handle N. The motion ofthis handle is by preference limited in both directions. When v 'turnedbackward, a pin may be employed` to. Y

arrest itsl motion, and when turned forward its motion is arrestedagainst the pivotedv plunger O. This plunger' is supportedupon a pivotedarm, as shown, and when swung in- -ward it will bel concentric with thecenter of the ejector E l When swung outward, as shown in Figs. 1 and 2,it serves to arrest the downward motion of the screw bythe handle Ny.

coming in contact with its upper portion.y

The operation of the mechanism is substantially the same as thatpreviously patented to n The cover is raised to theposition shown shankare lput in position.

ejector E being depressed bythe motion of the crank, these parts areforced down upo'n it.

The plunger O, when'it is swung over the clothv and shank, is depressedby the hand forcingy them into the'cavity made to receive them.

The mold is then placed in positionin the button`forming cap L and themachine closed and locked. The revolution of the crank then raises the.ejector, closes the parts between the ejector, the buttonforming tube D,and the cap L. The eyeleting-spindle M is then depressed by moving thehandle, and the button is completed. By withdrawing the bolt the cap isj raised and the button can be removed.

When it is desired to form a button of a dif ferent size, the parts D EL', (shown in Fig. 4,) ofproper size, are substituted for the parts D EL. The cap L is preferably held in position by a set-screw, I?. In thismachine, asin that previously described, I nd it important to have abeveled rim, g, in the button-forni- I do not limit myself to thearrangement of parts shown--for instance, the plunger O need not bepivoted upon the machinee-though I prefer the form shown.

What I claim as my invention,and desire to secure by Letters Patent, is-

1; The combination of the base A, cover B, independent ejector E, andmechanism for raising said independentejector through thebutton-for1ning tube, substantially as described.

2. The combination,inabutton forming inachine, of a supporting-basehaving a cylindrical opening for supporting t-he button-formingcylinder, a button-forming cylinder, D, made to the size of the buttondesired, an ejector, E,

to [it the same, a capor cover containing button-forming mechanism andhaving a cavity to receive cap L, in different sizes,provided withmechanism for turning the edges of the cloth, of identical exterior butvarying interior diameters, and mechanism for supporting the cover uponthe base, substantially as described.

3. The combination of the frame A, carrying button-forming cylinder Cand ejector E, the pivoted cover carrying the buttonforming cap and theeyeletingspindle M, and a stop supported upon the base ofthemachine,against which the handle of the eyeleting -plunger strikes inits operation, thereby limiting the motion ofthe eyeletingeplunger,substantially as described.

4. Thecombination,in a button-forming niachine, of the base A, thebuttonforming cylindcr D, the ejector E, and the plunger O, pivoted uponthe base A, whereby it may be swung into position to operate indepressing the cloth, substantially as described.
